Voters nationwide reported some 1,100 problems with electronic voting machines on Tuesday, including trouble choosing their intended candidates. There were also several dozen voters in six states...who said the wrong candidates appeared on their touch-screen machine's checkout screen. In many cases, voters said they intended to select John Kerry...but when the computer asked them to verify the choice it showed them instead opting for President Bush. The reports did highlight computer scientists' concerns about touch screens, which they say are prone to tampering and unreliable unless they produce paper records for recounts. Roberta Harvey, 57, of Clearwater, Fla., said she had tried at least a half dozen times to select Kerry-Edwards when she voted Tuesday at Northwood Presbyterian Church. After 10 minutes trying to change her selection, the Pinellas County resident said she called a poll worker and got a wet-wipe napkin to clean the touch screen as well as a pencil so she could use its eraser-end instead of her finger. Harvey said it took about 10 attempts to select Kerry before and a summary screen confirmed her intended selection. The Election Protection Coalition received a total of 32 reports of touch-screen voters who selected one candidate only to have another show up on the summary screen, Cindy Cohn, legal director of the Electronic Frontier Foundation, a coalition member.
